"Listening to @realDonaldTrump having fun and swinging from the hips on @foxandfriends and wondering why he hasn't been doing this more. This works. He's the best promoter of his own record and people," Hewitt wrote.

Others were not nearly as supportive. "You can practically hear the spittle flying out of Trump's mouth," liberal columnist Ana Marie Cox tweeted.

James Poniewozik, TV critic for The New York Times, said he was sure that the Trump interview "was a hit with the actual Fox & Friends audience."

"The way he speaks -- the rants, complaints, grievances -- is basically an EEG of how watching a day of Fox is designed to make the viewer feel. It's like the inner monologue of the show," Poniewozik tweeted.
